Solved: Re: Load Multiple Class

Antoine553 · ‎07-05-2017

I'm actually following the tutorial of Pierre Fay but i'm working on a page in the admin side but i don't get the correct way to put a second class "Mymodule\Admin_Page\Block\Contactlists" idea someone ?

<?xml version="1.0"?>
    <page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
        <head>
			<title>Module Mymoodule</title>
        </head>
        <body>
            <referenceContainer name="content">
                <block class="Magento\Backend\Block\Template" template="Mymodule_AdminPage::nettoyage.phtml"/>
            </referenceContainer>
        </body>
    </page>

check namespace and xml block name

namespace Mymodule\Admin_Page\Block\Adminhtml;

in xml you write

Mymodule\AdminPage\Block\Adminhtml\Contactslist

Clear difference Admin_Page and AdminPage

        </referenceContainer>
    </body>
</page>

Now create your block class,

You can extend base class like this,

<?php
namespace Mymodule\AdminPage\Block\Adminhtml;

class Contactlists extends \Magento\Backend\Block\Template
{
  public function mycustom(){
      //your code
      return;
  }
}

Remove var/generation folder.

I tried but if i delete the :

class="Magento\Backend\Block\Template"

It no longer work probably because he need it in the admin side.

@Antoine553

in admin side you need to use Magento\Backend\Block\Template;

    {
        echo 'helloworld';
    }
}

<?xml version="1.0"?>
    <page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
        <head>
			<title>Module Mymodule</title>
        </head>
        <body>
            <referenceContainer name="content">
                <block class="Mymodule\AdminPage\Block\Adminhtml\Contactslist" template="Mymodule_AdminPage::nettoyage.phtml"/>
            </referenceContainer>
        </body>
    </page>

Fatal error: Cannot redeclare class Mymodule\\AdminPage\\Adminhtml\\Block\\Contactslist in /home/mademonstration/public_html/newmagento3/app/code/Mymodule/AdminPage/Block/Adminhtml/Contactslist.php on line 12

@Antoine553 which is your line no. 12,

You can set class definataion in your block file like this,

<?php
namespace Mymodule\AdminPage\Block\Adminhtml;

use Magento\Backend\Block\Template;

class Contactslist extends Template
{
    public function test()
    {
        echo 'helloworld';
    }
}
